IN THE SUPREME COURT OF THE STATE OF DELAWARE
KEVIN STEVENS, § § No. 298, 2024 Defendant Below, § Appellant, § Court Below: Superior Court § of the State of Delaware v. § § Cr. ID No: 2212008180 (N) STATE OF DELAWARE, § § Appellee. § §
Submitted: May 14, 2025 Decided: August 11, 2025
Before VALIHURA, TRAYNOR, and GRIFFITHS, Justices.
Upon appeal from the Superior Court of the State of Delaware. AFFIRMED.
Robert M. Goff, Esquire, Elliot M. Margules, Esquire (argued), OFFICE OF THE PUBLIC DEFENDER, Wilmington, Delaware, for Appellant Kevin Stevens.
Carolyn S. Hake, Esquire (argued), DELAWARE DEPARTMENT OF JUSTICE, Wilmington, Delaware, for Appellee State of Delaware. TRAYNOR, Justice:
The defendant was tried and convicted in the Superior Court for driving a
motor vehicle while under the influence of intoxicating drugs and driving with a
suspended license. In this appeal, he argues—as he did in the Superior Court—that
the court erroneously admitted the State’s toxicology evidence, which was derived
from two blood tests showing the presence of intoxicating drugs in the defendant’s
blood when he was arrested. More specifically, the defendant contends that the State
did not lay a sufficient foundation for the challenged evidence because it did not first
introduce documents showing that the machines from which the blood-test results
were derived were calibrated and in good working order. By allowing the results
into evidence, the trial court, so the defendant argues, abused its discretion. He asks
us to reverse his conviction.
In this opinion, we decline the defendant’s invitation to adopt a bright-line
rule requiring the introduction of calibration records before blood-intoxication
evidence is offered by expert witnesses familiar with the working order of the
machines they have used to test a defendant’s blood. And for all the reasons given
below, we conclude that the Superior Court did not abuse its discretion when it
overruled the defendant’s objections to the challenged evidence. Thus, we affirm
the defendant’s convictions.

A
On the evening of December 18, 2022, Alexander Batt was sitting in his car
in the parking lot at Branmar Plaza in Wilmington when he witnessed a white pickup
truck driving erratically. Batt noticed the truck after it “almost hit”1 his car and then
ran into another parked car with enough force to cause the car to move and damage
its bumper.2
Batt followed the truck. He observed the truck stop at a green light at an
intersection, and in the truck’s side mirrors, he saw the driver, later identified as
Kevin Stevens, hunched over the wheel. When the light turned red, the truck
proceeded through the intersection, narrowly avoiding another car. Batt continued
to follow Stevens’s truck, which then turned into the Graylyn Shopping Center on
Marsh Road. Stevens parked the truck across two open parking spots near the Rite
Aid pharmacy in the shopping center and remained slumped over for 20-30 seconds
before he exited the truck and stumbled into the Rite Aid. Batt followed Stevens
into the Rite Aid, where he observed him slumped over and asking where he could
find the dog food. Stevens then fell over, and Batt asked the store manager to call
the police.
1 App. to Opening Br. at A33. 2 A visual inspection of the truck later conducted by police, however, revealed no obvious signs of damage. 3 Trooper Sean Setting of the Delaware State Police responded to the call from
the Rite Aid. Batt directed Setting to Stevens and told Setting what he had seen
before arriving at the Rite Aid. Setting asked Stevens if he had consumed any
alcohol or drugs, and Stevens said that he had not. Setting conducted horizontal
gaze nystagmus and vertical gaze nystagmus tests,3 but observed none of the signs
indicating intoxication in either test, leading him to conclude that Stevens’s
condition was “not alcohol related.”4 Setting attempted to administer other field
sobriety tests, but was unable to do. According to Setting, Stevens “seem[ed] like
he fell asleep a few times[,]” was “slouched over[,]” and was “almost not
coherent[.]”5 Setting arrested Stevens for suspicion of driving under the influence
of drugs.
After taking Stevens to the police station, Setting obtained a warrant to collect
a sample of Stevens’s blood. The blood sample was turned over to the Delaware
Division of Forensic Services, and chemical testing of Stevens’s blood revealed the
presence of flubromazepam, which is a benzodiazepine derivative,6 and fentanyl.7
Stevens was charged with driving a vehicle under the influence of drugs under 21
3 Nystagmus tests are standardized field sobriety tests conducted by asking the subject to focus on an object such as a pen or a light, then moving the object while looking for signs of involuntary eyeball movement—nystagmus—indicative of intoxication. See generally State v. Ruthardt, 680 A.2d 349, 352–53 (Del. Super. Ct. 1996) (describing the horizontal gaze nystagmus test). 4 App. to Opening Br. at A87. 5 Id. at A88. 6 See id. at A181–82, A291. 7 Id. at A291. 4 Del. C. § 4177 as well as driving with a suspended license under 21 Del. C. §
2756(a). A jury trial was held in March 2024.

Stevens’s trial strategy was twofold. As one part of his defense, he took the
stand to present his own account of the night of December 18, 2022. He testified
that he was in “a bad state of mind”8 that evening because he had recently separated
from his girlfriend and “just went out to get the dog some treats.”9 Stevens testified
further that he had left the Acme because the prices were too high and denied hitting
anything in the parking lot with his truck. He claimed that he parked his truck
sideways at the Rite Aid because he was in a hurry and denied that he had fallen
over inside the store. Stevens told the jury that he thought Setting was repeatedly
asking him to do field sobriety tests because “he was trying [to] get me to mess up.”10
He added that he would have been unable to complete the tests because he was
wearing steel-toed boots and had recently broken his kneecap. Stevens characterized
his demeanor in the Rite Aid as “just hanging my head down like shaking it”11 in
response to Setting’s repeated requests that he take field sobriety tests.
8 Id. at A217–18. 9 Id. at A218. 10 Id. at A223. 11 Id. at A225. 5 Of greater moment in this appeal, Stevens’s defense also took aim at the
admissibility of the State’s toxicology evidence. Stevens’s blood had been first
tested using an enzyme-linked immunosorbent assay (“ELISA”), a preliminary test,
the results of which are subject to confirmation. The ELISA results indicated the
presence of a benzodiazepine and fentanyl in Stevens’s blood sample. The ELISA
results were confirmed using a liquid chromatograph tandem mass spectrometer
(“LC-MS/MS”). The State called numerous witnesses from the Division of Forensic
Services to establish the chain-of-custody of Stevens’s blood sample and to provide
foundation testimony to introduce the preliminary ELISA results and the LC-
MS/MS results confirming the presence of a benzodiazepine, in this case
flubromazepam, and fentanyl in Stevens’s blood sample.
Grant Fehnel, an analytical chemist at the Division of Forensic services,
testified that he had performed the preliminary ELISA test on Stevens’s blood
sample. He explained that although the machine used for ELISA testing does not
undergo tests to ensure that it is calibrated before every sample is run, there are
“quality control samples” run during the testing of live samples to ensure accuracy.12
He further explained that the machine produces raw data during testing that may be
used to verify the accuracy of the test results. During Fehnel’s testimony, Stevens
objected to the introduction of the State’s toxicology evidence. He argued that the
12 Id. at A142–43. 6 State had failed to provide sufficient foundation that the equipment used by the
Division of Forensic Services had been properly calibrated and was in working order
before and after it was used to analyze Stevens’s blood sample.13 The trial judge
overruled Stevens’s objection because he had not made a specific discovery request
for the bench notes showing that the machines were properly calibrated and had
failed to “raise[] the specter that this was anything other than ordinary, regular
tests . . . .”14
Three of the State’s witnesses testified about the LC-MS/MS results. One
witness, Matthew Fox, an analytical chemist who conducted a test on Stevens’s
blood using an LC-MS/MS, testified that the machine has a “daily calibration
requirement.”15 He added that the machine was calibrated the day that he conducted
the test of Stevens’s blood but that he did not have the documentation produced by
any calibration tests with him in the courtroom. He testified that the test he had
conducted confirmed the presence of fentanyl in the sample. Another analytical
chemist, Shronda Ellis, who had been tasked with conducting an LC-MS/MS test to
confirm the presence of benzodiazepine in the sample, testified that although the
lab’s LC-MS/MS machines are not necessarily calibrated every day, they are cleaned
and a “neat” sample is run to ensure that the chemist can see all of the peaks that he
13 Id. at A151–53 (objecting to testimony concerning ELISA results). 14 Id. at A154. 15 Id. at A173–74. 7 or she is supposed to see in the machine’s output before an actual sample is run.16
Although Ellis had documentation showing the results of the “neat” sample with her
in the courtroom on the day of trial, it was not introduced into evidence. The LC-
MS/MS results confirmed that a benzodiazepine—specifically flubromazepam—
was present in Stevens’s blood sample. Lastly, Jessica Smith, Delaware’s Chief
Forensic Toxicologist, whose job includes certification of final toxicology reports,
confirmed that LC-MS/MS machines undergo daily maintenance. This includes
“running calibrators.”17 She added that the lab’s acceptance criteria had been
followed in this case and that she had the raw data showing that this was the case in
the courtroom with her. This documentation, too, was not introduced into evidence.
Stevens raised the same objection—that the experts’ reliability opinions were
inadequate and thus the toxicology evidence was inadmissible for lack of
foundation—during the testimony of each of the three witnesses that testified about
the reliability of the LC-MS/MS results, and the trial judge overruled each objection
for the same reasons.18
16 Id. at A184. 17 Id. at A201. 18 Id. at A167, A180, A194. 8 C
Stevens was convicted of both driving under the influence of drugs and
driving with a suspended license. Stevens moved for a new trial, augmenting the
argument that he had made at trial and arguing that the State’s foundation for the
admission of the blood intoxication results was insufficient under this Court’s
decision in McConnell v. State, an opinion that addressed the admissibility of
intoxilyzer evidence in driving-under-the-influence-of-alcohol cases.19 McConnell
requires that the State lay foundation showing that the machine that generated the
result in question was “operating accurately before and after testing the breath of the
defendant on trial.”20 This requirement, according to defense counsel, applies with
equal force to the LC-MS/MS results introduced in this case.
The Superior Court denied Stevens’s motion. The court noted again that it
was unclear whether defense counsel had requested the bench notes showing that
the machines were calibrated and in working order in discovery under Superior
Court Criminal Rule 16, but if he had and the bench notes had not been provided,
presumably any discovery dispute could have been resolved before trial.21 The court
also noted that numerous witnesses from the Division of Forensic Services had
testified that the machines were in working order and frequently calibrated, and
19 639 A.2d 74, 1994 WL 43751 (Del. Feb. 3, 1994) (TABLE). 20 Id. at *1. 21 Opening Br. Ex. B at 2. 9 when one witness offered to provide defense counsel with bench notes with this
information at trial, defense counsel demurred. Lastly, the court wrote that
McConnell was of no help to Stevens’s argument because, while that case requires
that the State show that an intoxilyzer machine was operating accurately before and
after it was used to test the defendant’s breath, it also states that “[i]n the absence of
evidence to the contrary, there is a presumption that the State Chemist acted carefully
and in a prudent manner.”22
Because this was his fourth DUI offense, Stevens was sentenced to two years
of incarceration, suspended after six months for probation. On appeal, Stevens
argues that the trial judge erred by permitting the State to introduce the results of the
confirmatory LC-MS/MS tests without proper foundation.23
II
Stevens properly preserved his objection to the introduction of the State’s
toxicology evidence at trial. We review a trial court’s evidentiary rulings for abuse
of discretion.24 “An abuse of discretion occurs when a court has exceeded the
22 Id. at 3 (quoting McConnell, 1994 WL 43751, at *1). 23 Stevens’s trial counsel objected to testimony concerning both the ELISA and LC-MS/MS results. Because Stevens’s appeal addresses only the LC-MS/MS results, we focus our analysis accordingly. See Supr. Ct. R. 14(b)(vi)(A)(3). 24 McGuinness v. State, 312 A.3d 1156, 1190 (Del. 2024). 10 bounds of reason in light of the circumstances, or so ignored recognized rules of law
or practice [] as to produce injustice.”25
III
The gist of Stevens’s argument on appeal mirrors the argument in his new-
trial motion. He contends that this Court’s decision in McConnell creates a “bright-
line rule”26 that, before toxicology results may be introduced at trial, the State must
“present the certifications of the State Chemist that the intoxilyzer machine was
operating accurately before and after testing the breath of the defendant on trial.”27
This rule, according to Stevens, applies equally in the context of LC-MS/MS blood
tests.
We have held that, “[w]hen . . . evidence is obtained from the use of a
scientific instrument, expert testimony is necessary to establish the reliability and
accuracy of the instrument.”28 Here, the State called three expert witnesses,
analytical chemists Matthew Fox and Shronda Ellis, and Chief Forensic
Toxicologist Jessica Smith, to testify about the reliability of the LC-MS/MS
machines used to test Stevens’s blood. Stevens does not contend that the State’s
25 Id. (quoting Chaverri v. Dole Food Co., 245 A.3d 927, 935 (Del. 2021)) (internal quotation marks omitted). 26 Opening Br. at 11–12. 27 Id. at 11 (quoting McConnell, 1994 WL 43751, at *1). 28 Tolson v. State, 900 A.2d 639, 645 (Del. 2006). 11 witnesses lacked the qualifications to testify about the reliability of the LC-MS/MS
machines. He instead contends that the content of these witnesses’ testimony was
itself legally insufficient. The State should have, according to Stevens, introduced
certifications of the State Chemist or other calibration data showing that the
machines were operating accurately instead of presenting “inadequate and
unnecessary”29 testimony concerning the machines’ calibration. We disagree with
Stevens’s assertion that the State’s foundation testimony was insufficient.
Central to Stevens’s argument is his contention that McConnell v. State
provides a bright-line rule that calibration data must be produced before LC-MS/MS
test results are admissible. But McConnell is readily distinguishable. In that case,
as we have mentioned, the defendant challenged the introduction of intoxilyzer test
results. McConnell’s argument was that, although the State presented the required
certification from the State Chemist that the machine was operating accurately
before and after it was used to take a sample of McConnell’s breath, the State was
also required to show that the “standard solutions” used to calibrate the intoxilyzer
machine by the State Chemist had been checked to determine their validity.30 We
held that, absent a showing from McConnell that the calibration checks were
improper, there was a “presumption that the State Chemist acted carefully and in a
29 Opening Br. at 14. 30 McConnell, 1994 WL 43751, at *1. 12 prudent manner.”31 In light of this presumption, we held that the trial court in that
case did not abuse its discretion when it admitted the results of McConnell’s
intoxilyzer test into evidence.
Intoxilyzer breath tests are administered in the field or at police stations by
police officers. To ensure that each intoxilyzer in use in Delaware is operating
accurately, each machine is calibrated periodically. The Superior Court helpfully
explained this process in Cedeno v. State:
Those with some familiarity with the law of DUI in Delaware . . . know that in order to satisfy the foundational requirements of scientific validity of the BAC results as recorded by the Intoxilyzer, Delaware case law requires that the State produce a “Certification Sheet” prepared by the State Chemist, certifying that on dates prior to and after the subject test, the machine was operating properly.
The Certification Sheet for each Intoxilyzer in service in Delaware is checked for calibration by the State Chemist periodically. The State Chemist runs known samples of .05 and .10 through the machine and records how close the machine reading is to the known sample. These readings, along with the date and time they are taken, are recorded on the Certification Sheet. In addition, the Chemist breath[es] into the machine and records the Chemist’s own result (hopefully zero).32
That our law requires the production of a certification sheet from the State
Chemist before intoxilyzer breath test results may be admitted is intuitive. These
machines are tools operated by police officers, not by the trained scientists who
31 Id. 32 Cedeno v. State, 2023 WL 6323598, at *2 (Del. Super. Ct. Sep. 27, 2023). 13 perform the calibration and certification of each machine. And at trial, testimony
supporting intoxilyzer results often comes from the police officer that administered
the test. It goes without saying that such police witnesses are not experts, as defined
by D.R.E. 702, who may testify as to the reliability of the device they were using to
conduct a breath test. Requiring a certification sheet from the State Chemist, the
contents of which are generally admissible without the need of live testimony from
the State Chemist through the business-records hearsay exception,33 provides a
check to ensure that the results generated from the machine used to analyze a
defendant’s breath sample are reliable.
LC-MS/MS blood intoxicant test results are different. These tests are
conducted in State laboratories by forensic chemists. These individuals are trained
experts who, unlike police officers using intoxilyzers, have knowledge of and
perform the calibration and maintenance of LC-MS/MS machines. Stevens’s
argument that, in addition to testimony from analytical chemists at the Division of
Forensic Services and the Chief Forensic Toxicologist that the LC-MS/MS machines
used were properly calibrated, the State must also provide the analog of certification
sheets from the State Chemist for these machines—such as the witnesses’ bench
notes—fails to recognize this distinction. It seems unnecessary, where there is a
qualified expert witness on the stand who can opine on the subject of the reliability
33 See, e.g., Best v. State, 328 A.2d 141 (Del. 1974). 14 of their laboratory equipment, that an additional hearsay document on which the
expert testimony is based be a foundational requirement. And as we mentioned
earlier, Stevens makes no argument that the State’s expert witnesses lacked the
knowledge and qualifications necessary to opine on the reliability of the toxicology
results.
In his reply brief, Stevens contends that the distinction between lay-witness
police-officer testimony and expert-analytical-chemist testimony is
“anachronistic”34 because police officers are now routinely offered as expert
witnesses. But Stevens provides no authority showing that police officers may be
offered as expert witnesses to testify about the calibration of intoxilyzer machines
in the same way that an analytical chemist might testify about the calibration of
laboratory machines.
Both cases cited by Stevens are unpersuasive. In Mooney v. Shahan,35 the
Superior Court noted that a police officer may be qualified as an expert with
specialized knowledge and training in administering nystagmus tests.36 Although
the court, reviewing a decision of the Court of Common Pleas, did also permit police
officer testimony that “a permanently implanted false tooth would not skew
34 Reply Br. at 9. 35 2001 WL 1079040 (Del. Super. Ct. Aug. 4, 2021). 36 Id. at *3. 15 intoxilyzer results[,]”37 it clarified that this testimony arose in the context of an
administrative hearing at the Division of Motor Vehicles. The Superior Court did
not analyze the police officer’s testimony under the rules of evidence because
“[a]dministrative hearings are not constrained by the rigid evidentiary rules which
govern jury trials.”38 Even so, the court held explicitly that the police officer in that
case “was not testifying as an expert.”39 And in State v. Bell,40 the State offered a
police officer as an expert witness on the administration of intoxilyzer tests. The
Court of Common Pleas excluded the breath test evidence in that case for the State’s
failure to show that the police officer in question was qualified to administer
intoxilyzer tests.41 The calibration evidence in Bell, on the other hand, was provided
by the State Chemist.42
The extent of foundation testimony necessary to admit the results of
laboratory tests such as LC-MS/MS into evidence was not at issue in McConnell.
To the extent McConnell is applicable, it stands for the proposition, as the Superior
Court noted, that when there is evidence from an expert witness such as the State
Chemist, an analytical chemist, or the Chief Forensic Toxicologist showing that a
machine used for scientific testing was calibrated, absent a showing to the contrary
37 Id. at *4. 38 Id. 39 Id. 40 2015 WL 1880591 (Del. Com. Pl. Apr. 23, 2015). 41 Id. at *2. 42 Id. at *2, *3 n.9. 16 by the defendant, we presume that such calibration was done “carefully and in a
prudent manner.”43
To be sure, under Rule 702, “the trial judge must make a preliminary
determination that the expert witness is able, as a factual matter, to provide the
proposed opinion.”44 This means that the trial judge, as Stevens correctly contends,
must be satisfied that expert testimony is “based on sufficient facts or data.”45 But
those facts and data need not be admissible.
An expert may base an opinion on facts or data in the case that the expert has been made aware of or personally observed. If experts in the particular field would reasonably rely on those kinds of facts or data in forming an opinion on the subject, they need not be admissible for the opinion to be admitted.46
Although the calibration data at issue here might in fact be admissible, the fact that
D.R.E. 703 permits an expert to testify based on that data without its admission is
fatal to Stevens’s argument that the introduction of the calibration data itself is a
foundational requirement for the introduction of LC-MS/MS results. The trial judge
heard testimony from three witnesses concerning the calibration of the LC-MS/MS
43 McConnell, 1994 WL 43751, at *1. 44 Perry v. Berkley, 996 A.2d 1262, 1270 (Del. 2010). 45 D.R.E. 702. Though Stevens does not cite Rule 702 in his opening brief, his argument appears to take aim at the admissibility of the experts’ calibration testimony for failure to satisfy the second of Rule 702’s requirements—that an expert’s testimony be based on sufficient facts or data. Reply Br. at 5. 46 D.R.E. 703. 17 machines. All three, basing their opinions on observations of either calibration data
or the results returned by “neat” samples as permitted by the rules of evidence,
testified that the machines were operating properly.
Stevens had numerous tools at his disposal to attack the State’s toxicology
evidence if, in fact, the calibration of the LC-MS/MS machines was faulty. Under
Superior Court Criminal Rule 16(b)(1)(F), the State is required to permit a defendant
to inspect “any results or reports of . . . scientific tests or experiments . . . that are
material to the preparation of the defense.” This rule plainly encompasses
calibration data for the LC-MS/MS machines, but the record does not show that
Stevens ever took advantage of this discovery tool.47 In fact, two witnesses stated
that they had physical copies of documents containing LC-MS/MS calibration data
or similar test results with them in the courtroom, but Stevens did not request it.48
D.R.E. 705(b) also permits a defendant to object to testimony by an expert witness
on the grounds that the expert lacks a sufficient basis for expressing an opinion and
47 The record does show that the State provided to Stevens the toxicology results, CVs of each expert witness, and chain of custody documentation for Stevens’s blood sample. Letter from James Betts, Esq. to Defense Counsel, State v. Stevens, No. 2212008180 (Del. Super. Ct. Feb. 23, 2023) (Dkt. 4). During the sidebar conference to discuss Stevens’s initial objection to the toxicology evidence, Stevens claimed to have made a broad discovery request under Superior Court Criminal Rule 16. The trial judge noted, however, that there was no specific request for bench notes or calibration data. App. to Opening Br. at A153–54. Nor does the record show that there was any discovery dispute before trial. The trial judge also gave Stevens the opportunity to raise the issue again post-trial if Stevens believed that there had been a “miscarriage of justice.” Id. at A154. Stevens did not do so. 48 App. to Opening Br. at A185, A202. 18 “conduct a voir dire examination directed to the underlying facts or data on which
the opinion is based.” Complementing D.R.E. 705(b), Superior Court Criminal Rule
16(b)(1)(G) requires the State to disclose, upon request from the defendant, “any
evidence which the State may present at trial under [D.R.E.] 702, 703, or 705.”
Stevens did not take advantage of these tools either.
In his reply brief, Stevens raises for the first time the argument that this court
should follow United States v. Sheppard,49 an unreported case from a federal district
court in Kentucky. This argument is waived.50 In any case, Sheppard is
distinguishable. In Sheppard, the trial judge excluded toxicology evidence where
the defendant had requested, but the government was unable to provide, calibration
data showing that the machines used to conduct a blood test of samples from victims
harmed by drugs allegedly supplied by the defendant were operating accurately. The
Sheppard court excluded the toxicology evidence because the calibration data was
unavailable altogether, so the testimony through which the government sought to
show that the testing was reliable consisted only of descriptions of the lab’s standard
practices.51 Here, by contrast, the State’s witnesses testified in reliance on actual
49 2021 WL 1700356 (W.D. Ky. Apr. 29, 2021). 50 See Supr. Ct. R. 14(b)(vi)(A)(3). 51 Sheppard, 2021 WL 1700356, at *5 (“Simply, [the expert’s] reliance on [the lab’s] standard procedures is not enough to establish, by a preponderance of the evidence, that the . . . testing was done properly.”). 19 calibration data concerning the machines and tests at issue—data that was available
and could have been obtained by the defense.
To sum up, McConnell provides no bright-line rule that a certification sheet
from the State Chemist or other calibration data must be produced before blood-
intoxicant test results from LC-MS/MS machines may be admitted into evidence.
Nor do our established rules of evidence.52 In light of the fact that the court heard
extensive testimony from expert witnesses based on their observations of the
calibration data indicating that the machines were properly calibrated, and that
Stevens presented no evidence showing that this testimony was not based on
sufficient facts and data, we conclude that the Superior Court did not abuse its
discretion in admitting that testimony and the LC-MS/MS results contained within
it.
52 Even if our rules of evidence suggested otherwise, the General Assembly has supplemented these rules in DUI cases. The toxicology evidence may well have been introduced under 21 Del. C. § 4177(h)(1), which provides that
[f]or the purpose of introducing evidence of a person’s alcohol concentration or the presence or concentration of any drug pursuant to this section, a report signed by the Forensic Toxicologist, Forensic Chemist or State Police Forensic Analytical Chemist who performed the test or tests as to its nature is prima facie evidence, without the necessity of the [expert witness] personally appearing in court.
So long as the report meets certain criteria as defined in the statute, the toxicology results contained within are prima facie evidence of intoxication—subject to challenge by the defendant. Because we determine that the State’s toxicology evidence was admissible under the traditional rules of evidence, we do not address its introduction under this alternative route. 20 IV
For the foregoing reasons, we affirm Stevens’s convictions.
